an editorial interpolation
First entry in the series of words I hear people use and that I tend to gloss over because I don’t know precisely what it means and neither, I suspect, do they…
I’m guessing that the usage most people intend is:
an established rule, tradition, or custom
but I’m open to being further educated on it. I can’t recall the last time I heard it in a script or on the radio, but I know I’ve heard it at least twice in the office in the past 2 months.
